# Battery Testing vs Battery Watcher

Battery Testing and Battery Watcher both sit at 4.5 stars, but that hides the real split: 71% of Battery Watcher's written reviews are positive against 23% of Battery Testing's. Battery Watcher also leads on ads (none vs shown) and iOS requirement (11.0 vs 13.0). Battery Testing's advantage is ratings volume (12K vs 323). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Battery Testing sells 1 one-off in-app purchase and Battery Watcher sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Battery Testing against 4.5 for Battery Watcher. That said, the two scores are not equally well evidenced: Battery Testing has 12K ratings behind it against 323, so its average is the more settled of the two. Written reviews are what separate them: 23% of Battery Testing's written reviews are positive against 71% of Battery Watcher's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 2, 2026 and September 29, 2026 respectively.
